　　Pultrusion molding is a process method for continuously producing glass fiber reinforced plastic profiles with equal cross-section shapes and sizes. The process is: under the traction force of the production of molding equipment, the reinforcing materials (such as glass fiber untwisted roving, glass fiber continuous felt, etc.) are impregnated with the base material (such as unsaturated polyester resin, etc.) in accordance with a specific configuration, and then passed through the mold system and continuously cured in it, so as to continuously obtain a smooth surface,Glass fiber reinforced plastic profiles with stable size and extremely high strength.

　　Application of the main profiles of pultruded glass fiber reinforced plastic: urban railway three-rail protective cover and bracket, insulating support components, antenna column, high-voltage cable bridge, high-voltage power supply operating pole, generator radiator, stairs and handrails, operating platform, aisle, fuel tank, power distribution board and power distribution room, drainage system, berthAnd submarine identification signs, pressure rods in trains and automobiles, corner panels, highway guardrails, sound-absorbing panels, anti-glare panels, packing brackets in towers, filter plate brackets, cold storage frame materials, etc.

　　Pultruded glass fiber reinforced plastic series products are made of extruded glass fiber reinforced plastic crossbars that pass through the pultruded glass fiber reinforced plastic load-bearing rods, which can disperse and adjust the force of the load-bearing rods and fix them. The excellent characteristics of pultruded glass fiber reinforced plastic can meet the requirements of a variety of occasions, and are widely used in petroleum, chemical industry, electric power, marine exploration, electroplating, shipbuilding, water treatment, papermaking, wine making, pharmaceutical and other industries' working platforms, equipment platforms, stair pedals, ditch covers, bridge plates, filter plates,Packing brackets, etc., are ideal load-bearing components in corrosive environments.
